This is the RFID transponder circuit we are using, and I would like you to check the schematic connections to see if they are correct.
The circuit is catered for both self-powered and external (3.6V) powered configurations
Self-power configuration - R37 = DNP and connect 0 ohms to R35.
External (3.6V) power configuration – R35 = DNP and connect 0 ohms to R37.
Please let me know if my configurations are correct.
Hello @pragashsangaran,
Hope you are doing well.
For UCODE G2iM, OUT pin is a digital output that can be used for tamper loop, a small external circuit or as indicator; these configurations require VDD pin to be externally suppled.
If you populate R35, it will introduce a galvanic connection that will activate the "tamper indicator" bit, as per Tag Tamper Alarm feature (please see AN10940 FAQs on UCODE G2i, Chapter 16). Is this the intended purpose for your application?
For external supply, the following configuration is required:

Eduardo.
